C.  INSTALLATION AND TEST

6.  Unpacking

6.1

Upon receipt of the equipment, proceed as follows:

1

Unpack each container and visually inspect it for signs of damage. If the equipment has been
damaged in transit, immediately report the extent of damage to the transportation company and
to PairGain. Order replacement equipment if necessary.

2

Check the contents versus the packing list to ensure complete and accurate shipment. If the
shipment is short or irregular, contact PairGain as described in Section 9. If you must store the
equipment for a prolonged period, store the equipment in its original container.

7.  Turn-Up and Testing

7.1

Install COT Channel Units

1

Insert each FLC-704 Channel Unit into the COT shelf.

All LEDs on the Channel Unit will turn on for approximately 1/2 second, then scan from top to
bottom, then flash all on, then off.

2

After the system has powered up, established HDSL synchronized communications, and no calls
are in progress, verify that the Channel Unit front panel indicators ACTIVE 1 through
ACTIVE 8 and FAULT LEDs are all off.

7.2

Test Subscriber Circuits.  Test each subscriber circuit by placing and receiving calls; ACTIVE 1
through 8 LEDs track call progress.

8.  Troubleshooting

8.1

Table 3 on page 8 provides troubleshooting procedures based on indications displayed by the front
panel indicators of FLC-704 Channel Unit.
